本文详细介绍了CentOS6.4系统中安装LAMP服务并对其进行配置的过程,即安装Apache+PHP+Mysql,参照了网上大神的设置,其他Linux发行系统可以参考~
在本文中部分命令操作需要root权限,输入‘’命令后输入密码即可切换root身份。
设置文件允许80端口和3306端口。因为80端口是http协议所使用的端口,如果防火墙禁止80端口的话,网站配置好了也无法从外网访问。3306端口是MySql数据库的默认端口。使用VIM打开iptables文件并添加规则:
<span 1</span> <span 打开iptables文件进行修改 </span><span 2</span> vim /etc/sysconfig/<span iptables </span><span 3</span> <span 4</span> <span 加入下列两行 </span><span 5</span> -A INPUT -p tcp -m state --state NEW -m tcp --dport <span 80</span> -<span j ACCEPT </span><span 6</span> -A INPUT -p tcp -m state --state NEW -m tcp --dport <span 3306</span> -j ACCEPT
添加好后文件应该如下图,如果以前修改过该文件责可能和笔者的图中略有不同:
2. 关闭SELINUX
中提供的()系统。对于目前可用的 安全模块来说,SELinux 是功能最全面,基本上都是用负载均衡设备做流量分发,对外仅开放了仅有的几个端口。所以综合安全性和复杂性来说,SELinux的性价比并不高。修改文件关闭SELinux,设置后如图:
<span 1</span> vim /etc/selinux/<span config </span><span 2</span> <span 3</span> <span 注释掉如下两行,在行首添加#注释。 </span><span 4</span> SELINUX=<span enforcing </span><span 5</span> SELINUXTYPE=<span targeted </span><span 6</span> <span 7</span> <span 在后面增加: </span><span 8</span> SELINUX=disabled
’重启系统。
<span 1</span> <span 通过yum软件包管理器安装MySql,管理器会自动安装依赖项,遇到询问直接输入y确认,直到显示“Complete!”完成。 </span><span 2</span> <span yum</span> <span install</span> mysql mysql-<span server </span><span 3</span> <span 4</span> <span 启动MySql </span><span 5</span> /etc/init.d/<span mysqld start </span><span 6</span> <span 7</span> <span 设置MySql服务为开机启动 </span><span 8</span> <span chkconfig mysqld on </span><span 9</span> <span 10</span> <span 复制MySql默认配置文件,直接覆盖/etc/my.cnf </span><span 11</span> <span cp</span> /usr/share/mysql/my-medium.cnf /etc/my.cnf
MySql设置:
<span <span 输入如下命令后需要连续输入两次密码确认,有询问输入Y同意即可,成功后显示</span></span><span Thanks for using MySQL!。</span>
<span mysql_secure_installation</span>
设置成功后需要重启MySql服务:
<span 1</span> /etc/init.d/<span mysqld stop </span><span 2</span> /etc/init.d/mysqld start
2. Apache服务的安装和配置
<span 1</span> <span 安装httpd </span><span 2</span> <span yum</span> <span install</span><span httpd </span><span 3</span> <span 4</span> <span 启动Apache服务 </span><span 5</span> /etc/init.d/<span httpd start </span><span 6</span> <span 7</span> <span 编辑apache设置 </span><span 8</span> vim /etc/httpd/conf/<span httpd.conf </span><span 9</span> <span 查找 <span #ServerName www.example.com:80</span></span> <span 10</span> <span 修改成 <span ServerName</span> <span www.XXXX.com:80</span></span> <span 11</span> <span 其中的“www.XXXX.com”自己的域名,没有可设置为localhost,如图 </span><span 12</span> <span 13</span> <span 设置Apache服务开机启动 </span><span 14</span> <span chkconfig httpd on </span><span 15</span> <span 16</span> <span 重启Apache服务 </span><span 17</span> /etc/init.d/httpd restart
3.安装PHP
<span 遇到询问直接输y确认 </span><span yum</span> <span install</span> php
安装PHP插件:
<span 插件包括MySql支持等,遇到询问一如既往的y确认~~ </span><span yum</span> <span install</span> php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt
安装完成后不要忘了重启Apache和MySql:
/etc/init.d/<span mysqld restart </span>/etc/init.d/httpd restart
到此软件的安装就结束了,接下来进行配置和测试。
<span 1</span> <span 编辑文件Apache设置文件 </span><span 2</span> <span vi</span> /etc/httpd/conf/<span httpd.conf </span><span 3</span> <span 4</span> <span <span 44行:</span> 修改 <span ServerTokens OS</span> 为 <span ServerTokens Prod </span></span><span 5</span> <span 防止错误页显示操作系统名字 </span><span 6</span> <span 7</span> <span <span 76行:</span> 修改 <span KeepAlive Off</span> 为 <span KeepAlive On </span></span><span 8</span> <span 允许程序性联机 </span><span 9</span> <span 10</span> <span 83行:</span> 修改 <span MaxKeepAliveRequests 100</span> 为 <span MaxKeepAliveRequests 1000</span> <span 11</span> <span 增加同时连接数 </span><span 12</span> <span 13</span> <span <span 331行:</span> 修改 <span Options Indexes FollowSymLinks</span> 为 <span Options Includes ExecCGI FollowSymLinks </span></span><span 14</span> <span 允许服务器执行CGI及SSI,防止列出目录 </span><span 15</span> <span 16</span> <span <span 338行:</span> 修改 <span AllowOverride None</span> 为 <span AllowOverride All </span></span><span 17</span> <span 允许.htaccess </span><span 18</span> <span 19</span> <span <span 402行:</span> 修改 <span DirectoryIndex index.html index.html.var</span> 为 <span DirectoryIndex index.php Default.php index.html index.htm Default.html Default.htm </span></span><span 20</span> <span 添加php默认文档 </span><span 21</span> <span 22</span> <span <span 536行:</span> 修改 <span ServerSignature On</span> 为 ServerSignature Off </span><span 23</span> <span 防止错误页显示Apache版本 </span><span 24</span> <span 25</span> <span <span 554行:</span> 修改 <span Options Indexes MultiViews FollowSymLinks</span> 为 <span Options MultiViews FollowSymLinks </span></span><span 26</span> <span 不显示树状目录结构 </span><span 27</span> <span 28</span> <span 759行:</span> 根据需要设置为 <span AddDefaultCharset UTF-8</span><span 或者 <span AddDefaultCharset GB2312 </span></span><span 29</span> <span 笔者大多数时候都在使用UTF-8编码,所以不进行修改 </span><span 30</span> <span 31</span> <span 796行:</span> 修改 <span #AddHandler cgi-script .cgi</span> 为 <span AddHandler cgi-script .cgi .pl </span><span 32</span> <span 允许扩展名为.pl的CGI脚本运行</span>
修改完成后保存退出并重启Apache,删除测试网页:
/etc/init.d/<span httpd restart <span 删除测试网页 </span></span><span rm</span> -f /etc/httpd/conf.d/welcome.conf /var/www/error/noindex.html
<span 1</span> <span 编辑php设置文件 </span><span 2</span> vim /etc/<span php.ini </span><span 3</span> <span 4</span> <span 946行:</span> 修改 <span ;date.timezone = PRC</span> 为 <span date.timezone =</span><span <span PRC</span> <span (去掉分号) </span></span><span 5</span> <span 6</span> <span 386行:</span> 修改 <span disable_functions =</span> 为 <span disable_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server,escapeshellcmd,dll,popen,disk_free_space,checkdnsrr,checkdnsrr,getservbyname,getservbyport,disk_total_space,posix_ctermid,posix_get_last_error,posix_getcwd,posix_getegid,posix_geteuid,posix_getgid,posix_getgrgid,posix_getgrnam,posix_getgroups,posix_getlogin,posix_getpgid,posix_getpgrp,posix_getpid,posix_getppid,posix_getpwnam,posix_getpwuid,posix_getrlimit,posix_getsid,posix_getuid,posix_isatty,posix_kill,posix_mkfifo,posix_setegid,posix_seteuid,posix_setgid,posix_setpgid,posix_setsid,posix_setuid,posix_strerror,posix_times,posix_ttyname,posix_uname </span><span 7</span> <span 设置PHP的禁用函数,若程序中需要使用的函数可以删除掉。 </span><span 8</span> <span 9</span> <span 432行:</span> 设置 <span expose_php = Off </span><span 10</span> <span 禁止显示php版本的信息 </span><span 11</span> <span 12</span> <span 745行:</span> 设置 <span magic_quotes_gpc = On </span><span 13</span> <span 打开magic_quotes_gpc,用于防止SQL注入 </span><span 14</span> <span 15</span> <span 229行:</span> 设置 <span short_open_tag = ON </span><span 16</span> <span 支持php短标签 </span><span 17</span> <span 18</span> <span 380行:</span> 设置 <span open_basedir = .:/tmp/</span> <span 19</span> <span 设置允许访问的目录和/tmp/目录,防止php木马跨站</span>
修改完成保存后重启服务:
/etc/init.d/<span mysqld restart </span>/etc/init.d/httpd restart
输入“
<span 1</span> <?<span php </span><span 2</span> <span phpinfo</span><span (); </span><span 3</span> ?>
保存退出后在浏览器中输入localhost查看php信息:
apache.apache -R /var/www/html
